6
Q
f
A
Right Atrium
-Receives deoxygenated blood from the vena cavas
7
Q
g
A
Tricuspid Valve
-One way valve that allows blood to move from RT Atrium
to RT Ventricle

8
Q
h

Right Ventricle
-Pumps blood through the pulmonary semi-lunar valves an into pulmonary trunk which separates into the two pulmonary arteries

12
Q
l
A
Left Atrium
-Receives blood from pulmonary veins
13
Q
m

14
Q
n
A
Left Ventricle
- Pumps oxygenated blood to the rest of the body
- Strongest part of the heart
15
Q
